Introduction: Patients diagnosed with schizophrenia display deficits in Theory of Mind (ToM) and Emotion Perception (EP) even before the appearance of full-blown symptomatology. Methods: We evaluated ToM and EP in a male cohort consisting of 25 First Episode Psychosis (FEP) and 16 relapsed schizophrenic patients (CHRON) compared to 12 subjects in Ultra-high Risk (UHR) and 23 healthy controls (CTR). Furthermore, we measured the levels of Cortisol, Insulin like Growth Factor (IGF-1), TNF-a, TNF-b and several interleukins as potential biomarkers. Results: Deficits in EP and ToM were found in FEP, CHRON patients and UHR subjects compared to CTR. The impairments in these two domains seem to follow different patterns in the course of psychosis. EP was more impaired in subjects with a longer history of symptomatology whereas there was no statistically significant difference regarding ToM. On the other hand IL-4 was the only biomarker correlated to ToM and EP scores in two different samples of our study. Conclusion: Social Cognition (SC) domains are impaired in patients with psychosis as well as in UHR subjects compared to healthy controls. There are differences in the progress of ToM and EP deficits in the course of psychosis. Interleukins as IL-4 could correlate to SC.

Koro syndrome is a psychiatric disorder characterised, in its typical form, by acute and intense anxiety, with complaints in men of a shrinking penis or fear of its retraction into the abdomen and resultant death. Initially, this syndrome was described as a culture specific disorder. Sporadic cases referred to as the koro-like syndrome have been observed in western countries recently. They are more likely to appear in the context of a psychiatric or neurological disorder. The clinical course of culture bound koro syndrome is usually self limited, but in some cases it can be transient or take on a chronic or recurrent form, lasting from days to weeks, months or even years. We present two cases, one of a middle aged man whose koro-like symptoms have persisted for over 18 years in a relapse mode that is rarely observed, and one of a young schizophrenic, who also exhibits koro-like symptoms.
